Thermometry for a Kagome Lattice Dipolar Rydberg Simulator
Erik Fitzner, Igor Lesanovsky, Björn Sbierski
We propose an accurate thermometry approach for Rydberg atom tweezer arrays combining data from correlation and local susceptibility measurements with a theoretical high-temperatur…
Collective cluster nucleation dynamics in quantum magnets
Philip Osterholz, Fabio Bensch, Shuanghong Tang +4
Strongly interacting many-body systems exhibit collective properties that emerge from complex correlations among microscopic degrees of freedom. These cooperative phenomena govern…
High-temperature series expansion of the dynamic Matsubara spin correlator
Ruben Burkard, Benedikt Schneider, Björn Sbierski
The high-temperature series expansion for quantum spin models is a well-established tool to compute thermodynamic quantities and equal-time spin correlations, in particular for fru…
Dynamic correlations of frustrated quantum spins from high-temperature expansion
Ruben Burkard, Benedikt Schneider, Björn Sbierski
For quantum spin systems in equilibrium, the dynamic structure factor (DSF) is among the most feature-packed experimental observables. However, from a theory perspective it is ofte…
Pseudo-Majorana functional renormalization for frustrated XXZ spin-1/2 models with field or magnetization along the spin-Z direction at finite temperature
Frederic Bippus, Benedikt Schneider, Björn Sbierski
The numerical study of high-dimensional frustrated quantum magnets remains a challenging problem. Here we present an extension of the pseudo-Majorana functional renormalization gro…
Frustrated Quantum Spins at finite Temperature: Pseudo-Majorana functional RG approach
Nils Niggemann, Björn Sbierski, Johannes Reuther
The pseudofermion functional renormalization group (PFFRG) method has proven to be a powerful numerical approach to treat frustrated quantum spin systems. In its usual implementati…
